VX front springs

[Anthony]

I would like to run the VX on the track.

 

Car will have nitrons on a wide track.

 

Any thoughts on starting point for spring rates ?

 

Best regards

I think 260 - 300lb/in seems to be the general starting point. Depends on your front ARB size, etc.

Steve F ended up running 260lb on widetrack at the end of the season and much prefered them to standard rate (handling pack).

You mean you can drive these?

I thought it was just there to polish 😬

Hi Phil

 

Thanks a lot.

 

I have 280's (from x-flow) so looks like I am in the right ball park

 

Best regards

I do think I'm doing something wrong..... My car seems fastest on softer springs - 180lb ones. It seems to help keep the front planted. The back remains easy to catch. On 250's, I lose front grip. This does seem to be against the majority opinion though.

I also think that Alex's car has a lighter steering "feel" to my K engined Cat. It's very easy to drive. Perhaps that's why it's quick... easy to drive quick.

I think it's all balance between front and rear. As long as balance is maintained then you can go stiffer and stiffer and not suffer too much.

 

I think I like a softer rather than stiffer car too.

I like it without the the rear ARB.

 

I softened up the front ARB and that helped with the stiffer springs that were understeering a little more than the 180's with the 19mm ARB in the very slowest corner.

With the 180lb'ers I was getting drive on braking that is not good as the weight transfers etc.

 

Many run over 300lb fronts on VX's. In the VX race days some ran as much at 400lb and got the chassis cracking due to shock forces... I think those cars must have been very Stig like or should that be Pig like to drive...

Question - does dive equal more weight on the front and more grip? With the soft front springs, I felt I could lean onto the front tyres and turn in on the brakes more easily than with the harder springs which prefer a "brake in a straight line" technique. Downside of the softer springs seems to be that I have to be a bit more progressive on and off the brakes. It's almost like I brake softly to start the car diving and transfer the weight forwards then apply more braking.

 

Admittedly this only comes into play at Curborough where I know the place well enough to really drive hard - much harder than I ever do on a trackday.

 

*confused*

Could be true Alex esp at Curborough.

I think it is a what you like the feel of thing. For quicker lap times/£ I could not beat wider rubber and more traction through no rear ARB. This balance may shift again as I up the power stakes though.
